Variables
API - variables This page serves as a reference manual for all CTS602 QuickApp variables available through the nilan_var() function described on the scene page.
Each variable can be read by calling nilan_var("variable_name"), or by reading the NilanVars["variable_name"] associative array after calling nilan_var() without parameters.
Writable variables can be set by calling nilan_var("variable_name", new_value).
Naming convention The variable name suffix indicates the access level:
_ro — Read-only. The value can be queried but not changed. _rw — Read-write. The value can be queried and changed from a scene. _wo — Write-only. An action variable (e.g. reset button) that can only be written. _rw_inf — Read-write (info). Displayed as a label in the UI, but the underlying register may be writable.
